An industrial engineer designed a workstation where the seeing task was difficult because of the size of the components going into the assembly. The desired brightness was 150 foot Lamberts and the workstation was painted a medium green
having a reflectance of 52%.
fc (Please keep as an integer)
(2) By referring to the table in slide 7 (lecture 5), please estimate the required illumination if you repainted the workstation with a light cream paint:
(1) What illumination would be required at this workstation to provide the desired brightness ?
fc (Please keep as an integer)
In what way is plane polarized light different from an unpolarized light?
(III) A beam of light enters the end of an optic fiber as
shown in Fig. 23–58. (a) Show that we can guarantee total
internal reflection at the side surface of the material (at
point A), if the index of refraction is greater than about
1.42. In other words, regardless of the angle a, the light
beam reflects back into the material at point A, assuming
air outside. (b) What if the fiber were immersed in water?
